COLMAN J. SEMAN United States Patent M 3,279,763 MACHINE FOR MIXINGINGREDIENTS Colman J. Seman, 1409 Springlake Drive, Erie, Pa. FiledSept. 25, 1964, Ser. No. 399,309 Claims. (Cl. 259-14) This inventionrelates to .a mixer and loader for concrete, cement products and otherlike loose materials and, more particularly, to an improved machine formixing ingredients including loose materials such as cement products.

In the past there has been a problem of providing a machine to carry outan efiicient and fast mixing of ingredients such as loose mate-rials andcement products.

An object of this invention is to provide a device which can be used tocarry out an eflicient, rapid and thorough mixing operation for loosematerials such as cement products.

Another object of the invention is to provide a loading mechanismincluding a hopper which may be lifted easily and placed into positionfor loading a drum mixer.

Another object of the invention is to provide mixing drums situated inpairs on an axis of rotation, each drum having its central axis disposedat approximately 90 to the other so that they counter balance eachother.

A further object of this invention is to provide a rapid system ofmixing cement ingredients at a relatively low equipment cost.

Another object is to provide a tumbling type mixer for cement products.

Another object is to provide a process of mixing cement using a tumblingprinciple.

With the above and other objects in view, the present invention consistsof the combination and arrangement of parts hereinafter more fullydescribed, illustrated in the accompanying drawings and moreparticularly pointed out in the appended claims, it being understoodthat changes may be made in the form, size, proportions, and minordetails of construction without departing from the spirit or sacrificingany of the advantages of the invention.

In the drawings:

FIG. 1 is a perspective view of the loader in the invention;

FIG. 2 is a perspective view of the loader and fork lift truck incombination; and

FIG. 3 is a perspective view of the machine elements according to theinvention situated as in use.

Now with more particular reference to the drawings, the loader .10 isshown in FIG. 1 which is of a rectangular shape in cross section havinga top opening ;11 in which the ingredients are received. A motor -12which is located on the side is connected by means of a suitable driveto a riddling mechanism 11 or agitator which will sift the ingredientsas they are placed in the opening 11 supported on the loader by means oflinks -111 and vibrated by a suitable vibrating mechanism (not shown).The motor may be fixed to the side of the loader above the liftingsupports 15.

The lifting supports will be inclined upward from the rear of the loader110 just above the bottom thereof and inclined upward and forward at anangle of about 45 These lifting supports 15 may be made of angle iron orsome similar material and be provided with generally flat lower sides toaccommodate the forks of a lifting truck.

The front of the loader will be provided with an unloading door 13 whichwill take up about half of the front end. Connected to the unloadingdoor v13 which is hinged along the top will be a hopper door release bar24 which when pulled by door release line 23 will unload the hopper. Thefront side of the loader has a rearward- =ly inclined front end 16 whichextends from the unload- 3,279,763 Patented Oct. 18, 1966 .ing door 13upwardly and to the load opening 11. Direct- -ly above end 16 andconnected to the front of the opening '11 will be a bar spacer :17 whichsupports the door lifting arms .14. These arms 14 project forwardparallel to the loader lifting supports 15 adjacent thereto.

In FIG. 2 a fork lift truck -18 is shown in position directly behind theloader .10 with the forks sliding in position under the loader liftingsupports 15. As the truck 18 begins to lift the loader 10 it tilts theloader until the lifting supports 15 are in a horizontal position alongwith the door lifting arms 14. The loader :10 will be raised and movedinto the position shown in FIG. 3.

In FIG. 3 two cylindrical tanks 19 and 20 are shown with an axle 26 attheir center supporting them. The drums are disposed at to each otherand supported on the drum support frame 25 which is triangular in shapeand has one frame member on each side of the drums .19 and 20. Thesedrums will be supported at the top angle by axle 26 with suitablebearings. A motor 30 with a gear and drive chain 29 running to asprocket 28 located between the drums rotate the drums and mix theingredients therein.

The loader 10 and mixing drum 20 are shown in loading position in FIG.3. As the fork lift truck 18 and loader :10 come in close proximity withthe drums the fork lift lifts the loader until the door lift-ing arms 14come in contact with the lugs 22 on the door 21. The lifting arms 14will automatically lift the door into a perpendicular position thusallowing the unloading door 13 to be moved into position for releasingthe contents from the loader 10 when door 13 is opened.

When the loader is in proper position for release the loader doorrelease line 23 may be pulled by the operator and the door release barwill lift and open the door [13 thus releasing the contents into thecylinder drums. After the completion of this operation the loader 10 isremoved by the fork lift truck 18 thus allowing the drum door 2-1 toclose. The cover locks .27 will be swung into position and clamped andthe cylinders will rotate so that the other cylinder drum -19 is readyfor loading. The same procedure is repeated until both drums are loadedand ready for the rotation mix.

The mixer is then driven so that the contents tumble from end to endthereby agitating the materials therein. It has been discovered thatsuccessful mixing of cement powder can be accomplished when the drumsare of such dimension that the length is approximately three times thediameter.

The foregoing detailed description has been given for clearness ofunderstanding only, and no unnecessary limitations should be understoodtherefrom, for some modifications will be obvious to those skilled inthe art.
